  2. Background Information http://www.pv.unsw.edu.au/Research/3gp_Surface_Plasmons.asp 2009 MSIC Richmond, VA

  3. Wave Importance 2009 MSIC Richmond, VA

  4. Nanotechnology Objectives Size and scale Wave properties 2009 MSIC Richmond, VA

  5. Instructional Strategies Anticipatory Set 1.1 Vocabulary 2009 MSIC Richmond, VA

  6. Basic Wave Vocabulary • absorption • amplitude • boundary phenomena (absorption, diffraction, reflection, refraction) • diffraction • energy • frequency • incident angle • interference • normal • period • reflected angle • refracted angle • reflection • refraction • Snell’s Law • wave • wave length • wave speed • Surface Plasmon Vocabulary • additional boundary phenomena (evanescent wave, surface plasmon) • critical angle (more advanced Snell’s Law) • evanescent wave • fiber optics ??? (as example of how total internal reflection is used) • laser • surface plasmon resonance • total internal reflection 2009 MSIC Richmond, VA

  7. 1.2. Basic index of refraction determination type lab using the substances we will be using for the total internal reflection gelatin lab.  Students have already calculated values and they can anticipate layering, etc. 2009 MSIC Richmond, VA
